page_load another handler?

can someone please explain why this code is not working as expected:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class temp : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write("foo<br>");
        this.Load += new EventHandler(temp_Load);

    }

    void temp_Load(object sender, EventArgs e)
    {
        Response.Write("bar<br>");
        Response.End();
    }
}

trying to add another handler for page Load event so that output would be:

foo<br>
bar<br>

EDIT:

The actual object disappears and is recreated on postback. – ggonsalv

so how can i than modify the method in memory so it makes new objects with that modified method?

for example i want to modify or add page_init handler on runtime for the next time the page loads?

You cannot modify the Load handler from withing the handler itself. It's too late as it is already executing. Why not simply calling a function as it doesn't make much sense of having multiple load handlers for the same page:

protected void Page_Load(object sender, EventArgs e)
{
    Response.Write("foo<br>");
    temp_Load(sender, e);
}

You need to register it in the Page_Init. By the time Page_load fires, it is toooooo late.
